Abstract: Mixed oxides of Mo-V-W-Cu were prepared by three different synthesis methods, namely, evaporation (EV), hydrothermal treatment (TH), and evaporation, followed by hydrothermal treatment (EV-TH). The catalyst samples were characterized by X-ray diffraction (XRD) and fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and N2 adsorption/desorption techniques. Subsequently, their catalytic performance Leia mais…

Abstract: The present treatment of water from aqueous solutions, reported from our research work, uses polyurea (PU) as a novel adsorbent. Specifically, the adsorption efficacy of PU was tested in dyes with different characteristics (Congo red (CR) and methylene blue (MB)). The PU membrane was obtained by a sol-gel chemistry Leia mais…

Abstract: Thermoplastic polyurethane (TPU) is a multiblock copolymer that exhibits an attractive shape memory effect (SME). Its morphology consists of a soft segment (SS), which corresponds to the polyol or a long-chain diol, while the hard segment involves the intercalation of a diisocyanate and a chain extender. Due to the Leia mais…

Abstract: Agarose has numerous applications in biochemistry and medical textiles. This study aimed to produce agarose graphene oxide-glycerol fibers and analyze their properties. The agarose gel was prepared by dissolving the polymer in 9:1 (v/v) dimethyl sulfoxide (DMSO): H2O, followed by spinning in an ethanol bath (1:1 (v/v) ethanol: H2O) Leia mais…

Abstract: Phase change materials (PCMs) such as paraffins are widely applied to store thermal energy. PCMs displaying high thermal conductivities are desirable because they crystallize or melt rapidly when the temperature in the environment changes, absorbing or releasing latent heat accordingly. In this work, we experimentally determined the thermal conductivity Leia mais…

Abstract: This article presents the results obtained in the evaluation of the joint action of the chemical inhibition (inhibitor) and the magnetic field, aiming to evaluate the possibility of reducing the minimal inhibitory concentration (MIC), seeking an increase in production in oil extraction wells, increasing the reliability of the guarantee Leia mais…

Resumo: O conforto e a saúde dos pés são aspectos fundamentais ao selecionar calçados adequados. O principal fator para alcançar esses objetivos é o amortecimento1 , que pode ser incrementado pelo uso de palmilhas de conforto, que sejam projetadas para oferecer suporte e absorver impactos durante a caminhada, reduzindo o Leia mais…
